Got a new tank and need to drill a 1” drain. Anyone know somewhere local that carries this size or better yet, lend me one? Any help would be greatly appreciated

I was looking last week or so but couldn't find anything local. So I ordered one. I drilled my tank last weekend, used it once. It's a 45mm. You can have it for a zoa frag. I'm in West Houston. PM me if ya want.

Lowe’s carries smaller sizes, but it’s very difficult to find larger ones around town. 1” might be here local. Where are you located? Has anybody tried Harbor Freight?

Looks harbor freight has a carbide hole saw. Looks similar to a diamond bit. Would that work?

To save you time... I went to Lowes, home depot, ace hardware, northern tools, and harbor freight.
Bulk Reef Supply may have some in stock online. Amazon does also.

You can, but you want to go very slow and keep a constant stream of water on the cut. You also want to rinse the cut site frequently. Best to use a corded drill instead of a battery powered one due to the length of time it takes to drill the hole. One thing is as the drill hole reaches the end you will need to start gently lifting up on the drill to reduce the pressure on the glass. This is to prevent the glass from chipping as the hole-saw punches through.

With the Harbor Freight or any cheap carbide or diamond bits, you will probably get at most 4-5 holes drilled before the tool dulls out and cutting efficiency goes to crap and could potentially cause damage to the glass as you are drilling it.

Thank you all for the replies and everyone who offered to lend me there's. I went ahead and just ordered a diamond bit online since everyone was on the opposite side of town. Thank you again!

What size did you go with for the 1”?

I think 45mm is what I normally use for ABS.
